I'll put aside the fact that I hate Apple and everything that Apple stands for, so the objective me says: yeah, that's an awesome price for that piece of kit. Apple makes a great product with solid software. Just be prepared to commit to the Apple ecosystem.
MacOS is *nix with a sexy UI built on top of it. I'd recommend playing around with Ubuntu before you invest the cash in a MacBook. But AirBooks are phenomenal systems, as much as the Apple hater in me hates to admit it.
